Cursor is an AI-native 🏷️#code-editor built by Anysphere Inc. and forked from 📝VS Code, integrating AI autocomplete, chat, and autonomous coding agents directly into the editing surface. Anysphere was founded in 2022 by four MIT classmates — Sualeh Asif, Arvid Lunnemark, Aman Sanger, and Michael Truell — and as of November 2025 the company had reached $1B ARR and a $29.3B valuation, with 📝OpenAI attempting an acquisition before Anysphere chose to raise instead.
Cursor 3, released in April 2026, is a complete redesign around managing fleets of autonomous coding agents — moving the primary workflow from editing code to directing, monitoring, and reviewing agents that handle implementation, testing, and deployment. Tab autocomplete runs on a Supermaven-derived engine with a 100K-token context window; multi-model support lets developers switch between GPT-5.4, Claude Opus 4.6, 📝Gemini, and proprietary models per task; cloud agents execute CI/CD pipelines and test suites in sandboxed infrastructure; and the editor speaks 📝MCP for connecting to external tools. In the competitive landscape Cursor occupies the IDE-native lane in a three-way split with 📝GitHub Copilot (multi-IDE extension) and 📝Claude Code (terminal-native agent), with 📝OpenCode as the primary 🏷️#open-source alternative. Developer-satisfaction polling has tracked differently from revenue — Claude Code leads at 46% "most loved," Cursor at 19%, Copilot at 9% — and the most common pattern among experienced developers is hybrid: Cursor or Copilot for daily editing, Claude Code for complex multi-file tasks. For MythOS users specifically, integration is covered in the 📝How to Use MythOS with Cursor guide and compared head-to-head with terminal-native alternatives in 📝Claude Code vs Cursor.
For the longest time everybody raved about Cursor. Then I started using it — and then I started using Claude Code and 📝Codex directly in the terminal. I lost interest entirely. The terminal-native workflow proved more powerful for how I actually build — multiple agents running in parallel, each with MCP access to 📝MythOS, no IDE layer between me and the work. Cursor solves a real problem for developers who think inside an editor. I don't anymore.
